Apache Shiro:
A comprehensive Java security framework that is very easy to understand? It's not a contradiction. Apache Shiro handles authentication, authorization, enterprise session management, and cryptography. Shiro offers a wide variety of options while also avoiding complexities by providing a clean and intuitive API.

http://workflowy.com/ - I use Workflowy a lot for for self-management & brainstorming while coding. If the project is also managed in Pivotal Tracker by a project manager, maintaining both causes content-duplication and I typically switch over to Pivotal. It's a shame since Workflowy is much better for structured documentation than tagged flat-lists (Pivotal) & a slew of disjoint feature/tech -specs spanning google docs, basecamp, etc. See http://ocdevel.com/blog/agile-trick-workflowy-pivotal-tracker

I have tested 3rd party tool which allows running processes under custom accounts. It is called “RunasSpc” http://www.robotronic.de/runasspcEn.html. License for 10 computers costs $90. It has visual interface “RunasSpcAdmin” to create encrypted files and avoid setting user and password as plain text. As a result I got encrypted file which contains program to run, options, username and password. It also allows checksum check to make sure executable is the same. Means if someone substitutes executable file we are going to run, this program will not start. I think we should try it on one of actual Jenkins jobs to finally make sure it suits our needs.

Scala:
Scala describes itself as where "object-oriented meets functional." On top of being OO, Scala is also a full-blown functional language. It usually runs on the Java VM, so Java and Scala classes can be freely mixed. Many frameworks including Akka, Finagle, and Play streamline the development of highly scalable and concurrent systems. If you want higher-order features that have been implemented in real-world projects but prefer not to wait for Java 8, use Scala today.

http://www.olark.com/: Olark, a small pop-up you place at the bottom of your website that allows you to chat with your customers, could be one way to differentiate the level of service you provide. If you aren't available, you can still use the tool to send you an email.

Sales & Marketing Tools:

http://www.hellobar.com/: Hello Bar let you place a bar at the top of your website that directs visitors anywhere you want. Direct Your Visitors and promote your website’s most important content.

https://www.kissmetrics.com/: Google Analytics tells you what happened, KISSmetrics tells you who did it. KISSmetrics fills this gap by showing you every action each individual did. Finally, you'll know who your most valuable customers are and how to get more of them. Make sure you check out its cohort analysis tools to measure visitor engagement over time.

First you must make sure you have the full set of the rar files. It will start from filename.part01.rar and end with filename.part21.rar (if the total is 21 files). Then right click on the filename.part01.rar and select "extract here". Notice the extracted file is much large than all 21 rar file combined. That means you had successfully extract it.

Download and install winrar, then just click on any part of the split rar files. Click and extract file.rar and it will autmatilcally extract the rest of the files and emrge them into one.

I use 7zip. highlight all files then right click extract to folder.

How to make multiple rar archives?

Using WinRAR, you can set part size, then WinRAR would divide the file into several parts.

Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. Uses multicast and/or unicast to inject xml data into an rrdtool frontend. Makes it very easy to make custom graphs as it was originally written to handle stats data from HPC clusters http://ganglia.sourceforge.net/

Subcon allows you to store your essential system configuration files in a subversion repository and easily deploy different configurations to machines in a cluster. It also features optional integration with SystemImager, enabling the deployment of system images and configuration in a single step. A flexible configuration file provides the ability to start, stop, or restart services or run arbitrary scripts when a change in a file or set of files is detected. http://code.google.com/p/subcon/

Splunk aggregate, index, search log files. Splunk also has ability to notify / alert when it see something in the log files, and possibility to do more interesting stuff.

QEMU virtualization (running multiple OSes / computers concurrently using one physical machine without dual booting). Similar to VMWare. I have page somewhere on this wiki on QEMU.

Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display. Redirecting the mouse and keyboard is as simple as moving the mouse off the edge of your screen. Synergy also merges the clipboards of all the systems into one, allowing cut-and-paste between systems. Furthermore, it synchronizes screen savers so they all start and stop together and, if screen locking is enabled, only one screen requires a password to unlock them all.

When are we going to move our Java reporting feature off the primary transactional database? Can we use a slave database?
When are we going to have a proper log server? When will we proactively fix defect rather than waiting for the customer to report it? (When will we have exception sent to us via email, SMS, SNMP trap?) When can we selectively crank up the log level for a particular session and have the log aggregated to the log server so that it is easy to debug the issue?
What are our current challenges? What can we do better?
Do you have any question for the team?
What do you wish to know better?

http://www.coarea.com/ - Nice idea. I could use it if I am looking to partner with a particular company. Both parties can review each others profile before deciding whether to begin discussions. Interesting site. There are many business directories out there, but most of them seem to be making money, so give it a shot and hopefully it goes well. You need to do 2 things to make sure the venture does not fail or get lost behind the competition:

Differentiate. What is different or better about your site than others? Some of the big guys are: Global Sources, Alibaba, Thomas Net, and Kompass. There are 1000's of others too.

Quality. Keep the users and content current, relevant, real. If you do not provide value or make it difficult to weed through the "junk" people will stop using your service.

Glyphdiff is a simple to use tool for comparing differences between two fonts, on particular glyphs. Just choose the fonts you'd like to compare, tune things like size, opacity, tracking, baseline, and more, and then see the fonts overlaid on each other to get a true idea of how similar (or different) they really are.

Booounce is a new take on the inspiration GIF and video collection. So many GIF sites out there have clunky, overly-busy designs that aren't exactly pleasurable to use. Booounce is different, though. The design is beautifully animated, but with a minimalist look and feel overall.

Airbus Group's Annual Report from 2015 is a fantastic take on what can be a very boring, stuffy corporate document. Their website includes interactive background video throughout, with links to key information like engagement, and even an interview with the CEO, Tom Enders. It can be a little tricky to navigate at first, but the overall UX makes up for it.

Crew is proposing that helping people sell leftovers could be the next magic business model. It's based on the idea of selling your by-products, proposed by Jason Fried of Basecamp, who has built a multi-million dollar business that makes significant revenue from selling left-overs.
